I'd like to help translating the game to Polish language. I did some translations in the past, the biggest so far being a machinery operation manual for a construction company - they paid me so I guess they were satisfied with my work :) of course I'd help you guys for free.
I assume the in-game text is not available to translators yet?

EDIT
I've found the templates for some stuff. Is anyone else translating to polish? Because I don't know if I should start translating and if so which part?

I see you are not used to the wiki code :D.
I fixed your add to the wiki list.
Also, I think you are the only Polish translator because no one else is listed and want to translate game/wiki.
You are welcome to begin wherever you want to !

I think we can host the batch on other sites, like framapad(french) or google drive for other users.
I do not know how crowdin work but we can use it.
Maybe share a .txt of the batch so we can work on it with different program.
